High Quality Content by WIKIPEDIA articles! You Don`t Know Jack (commonly abbreviated YDKJ) is a series of computer games developed by Jellyvision and Berkeley Systems, as well as the title of the first game in the series. YDKJ, framed as a game show "where high culture and pop culture collide", combines trivia with comedy. While primarily a PC and Mac-based franchise with over two dozen releases and compilations for those platforms, there have been a few entries released for consoles: two for the original PlayStation, and the 2011 release which had versions on the Xbox 360, PlayStation 3, Nintendo DS and Wii. In 2012, a social version of the game was released on Facebook.
